Cytological, seed and epidermal studies were carried out of 9 taxa belonging to 4 genera 6 species the tribe Eupatorieae. Chromosome counts 2 species-Adenostemma caffrum (n=10) A. mauritianum are reported for first time from Nigerian flora report Ageratum conyzoides (n=18) differed earlier reports. The cytotypes in is flora. pollen fertility test all plants studied high this revealed that meios...

Effects of the application potassium silicate (PS) and an arbuscular mycorrhiza fungus (AMF) (Glomus mosseae) were investigated on alleviating impacts drought stress Matthiola incana in a split-split-plot experiment two consecutive years. The main plot was assigned to at three levels irrigation (25%, 50%, 70%, field capacity) comparing with control (100% sub-plots AMF (0 200 g fungi pots) sub-s...

Root and shoot lead concentrations and the impact of chelating agents on these were investigated in two populations of the novel metallophyte Matthiola flavida. Plants were exposed in hydroponics to Pb(NO3)2, supplied alone, or in combination with citric acid, or EDDS. When supplied at concentrations expected to bind about 95% of the Pb in a solution containing 1-μM Pb (1000 μM citrate or 3.1 μ...

Aims The aim of the present study was to compare lead accumulation and tolerance among heavy metal hyperaccumulating and non-hyperaccumulating metallophytes. Methods To this purpose, we compared Pb tolerance and accumulation in hydroponics among calamine and non-calamine populations of Silene vulgaris, Noccaea caerulescens, and Matthiola flavida. We established the effects of Ca on Pb tolerance...

introduction heavy metals are largely found in dispersed form in rock formations. industrialization and urbanization have increased the anthropogenic contribution of heavy metals in the biosphere. heavy metal pollution not only affects the production and the quality of crops, but also influences the quality of the atmosphere and water bodies, and threatens the health and life of human beings. c...
